It’s official. While Americans had long had the honor (or, in this case, dishonor) of being the world’s biggest individual producers of carbon dioxide, Australians have overtaken them to claim the top spot[1]. In a recently released report, British risk consultancy Maplecroft placed Australia’s per capita CO2 output at 20.58 tons a year, which is about four percent higher than the United States. The other three top five biggest losers were Canada, the Netherlands (quite surprisingly) and Saudi Arabia. To Australia’s credit, it has committed to cutting greenhouse gas emissions by up to 25 percent by 2020 compared to 2000 levels, meaning that Americans could once again be labeled “World’s Worst Polluters” if we don’t get our acts together. To be fair, many individual Aussies, like our very own Jorge Chapa[2], are extremely green, and hopefully offset some of their homeland’s unsustainable ways.
